How can I view the Public Folder Tree Type in Exchange 2000/2003?
All MAPI clients can access the default Public Folders tree to read messages and store documents. When you create alternate public folder trees for applications or Web browsers to access, the alternate tree is not available to MAPI clients; however, applications and Web browsers can access the default Public Folders tree.
(Default PF Tree)
(Alternate PF Tree)
If MAPI clients is displayed, clients such as Outlook can access the hierarchy in addition to applications, Web browsers, and IFS shares. If General purpose is displayed, MAPI clients cannot see the hierarchy, but applications, Web browsers, and IFS shares can access the public folder hierarchy.
